Description

Miniature tri wheel farm vehicle transmission assembly

Relate to the field:

The utility model relates to the gear system technical field, is specifically related to a kind of miniature tri wheel farm vehicle transmission assembly.

Background technology:

At present, miniature tri wheel farm vehicle transmission assembly commonly used adopts a little projecting shaft that one reverse gearwheel is installed usually, and have two shifter bars, this structure operation complexity, also just like the patent No. be: 98221720 denominations of invention are: the motor tricycle change-speed box: the utility model discloses a kind of motor tricycle change-speed box, mainly comprise control mechanism and change speed gear box, change speed gear box comprises casing, establish input shaft in the casing, middle A axle, middle B axle, output shaft, input shaft and middle A between centers, middle A axle and middle B between centers are respectively equipped with a pair of reducing gear, output shaft is provided with sliding gear collar, sliding gear collar can realize respectively and the transmission that is connected of middle A axle and middle B axle that sliding gear collar drives output shaft and rotates under the manipulation of control mechanism, this complex structure, the cost height, function is few.

Summary of the invention:

The purpose of this utility model just provide a kind of simple in structure, cost is low, function is many, miniature tri wheel farm vehicle transmission assembly simple to operate.

To achieve these goals, the technical solution of the utility model is: a kind of miniature tri wheel farm vehicle transmission assembly comprises change speed gear box and joystick, on one of change speed gear box power-transfer clutch is installed, its constructional feature is: described change speed gear box comprises gear box casing, one, two and reverse gear shaft are installed on gear box casing, a reverse gear cliding gear, two third gear double-sliding gears are installed on one successively; First speed driven gear, whole miniature gears, third gear driven gear and the second gear driven gear of passing are installed on two successively; Hard-wired reverse gear shaft is the step axle on the described gear box casing, and reverse gear shaft one end is equipped with axle sleeve, and reverse dual-linked gear is installed on the axle sleeve.

As further improvement of the utility model, described power-transfer clutch gland is provided with belt pulley, and described joystick is single shifter bar.

The utility model adopts said structure, set up reverse gear shaft, reverse gear shaft is that a step axle reverse gear shaft one end is equipped with axle sleeve, reverse dual-linked gear is installed on the axle sleeve, improved reliability, can under vehicle operating or halted state, realize that takeoff output and joystick are single shifter bar by the belt pulley that is provided with on the power-transfer clutch gland, simple to operate.
